Abstract

A code division multiple access (CDMA) user device configured to dynamically allocating at least one wireless communication channel to permit a more efficient allocation of wireless communication channels when providing high speed data service. The CDMA user device is configured to receive data traffic from at least one data buffer in a base station. The CDMA user device is dynamically allocated at least one wireless communication channel based on an urgency factor. The urgency factor indicates the urgency of traffic data to be transmitted from the at least one data buffer in the base station to the CDMA user device.

Claims

1. A subscriber unit comprising:

circuitry configured to establish a packet data connection with the network to transfer packet data using at least one wireless channel;

wherein the circuitry is further configured to release all the wireless channels and subsequently transfer packet data using at least one wireless channel utilizing the packet data connection;

wherein the circuitry is further configured to transfer voice and packet data over a plurality of wireless channels; and

wherein the plurality of wireless channels varies in response to commands from a base station, wherein the commands are based on an urgency factor, U, for each of M buffers, where M is the total number of buffers used in the reverse and forward links and the urgency factor for the buffers servicing the forward links are calculated independently of urgency factors for the other buffers servicing the reverse links, and the buffers servicing each transmission direction of a particular connection between a particular one of the subscriber units and the base station are independent of one another.

2. The subscriber unit of claim 1 wherein the plurality of wireless channels are CDMA channels.

3. The subscriber unit of claim 1 wherein the plurality of wireless channels are TDMA channels.

4. The subscriber unit of claim 1 wherein the circuitry is further configured to receive layer 2 formatted data comprising a flag field.

5. The subscriber unit of claim 1 wherein the circuitry is further configured to transmit layer 2 formatted data comprising termination information.

6. The subscriber unit of claim 1 wherein the transfer of packet data is temporary.

7. The subscriber unit of claim 1 wherein the circuitry is further configured to transmit layer 2 formatted data comprising a sequence number and a control field.
